The Boltor is an automatic rifle that rapidly fires heavy bolts that can pin your foes to the walls.

The Boltor is a Tenno assault rifle with a unique characteristic of firing bolt projectiles, instead of conventional bullets. This weapon requires the user to take into account projectile travel time while aiming at targets, as well as the projectile drift, thus rendering the Boltor somewhat difficult to use effectively beyond medium ranges. Its high Puncture damage makes it an excellent close-quarters rifle against heavily armored targets.

The bolts, like the Kunai, stagger enemies, making it useful for crowd control.

The innate polarity can somewhat limit elemental modding potential, thus making it a less desirable polarity for elemental modding. If you wish to focus more on elemental damage, then it is recommended to either ignore the polarity or use Forma to turn it into a more suitable polarity.

An update on February 5, 2013 nerfed the Boltor to have 12.5 damage per shot. Soon after it was given a slight buff to 18.0 damage per shot, which is still less than the 25 on its initial release. On December 12, 2013, it was given a buff from 18 to 25 damage, same as when it was released.

On April 12, 2013, an update addressed the issue of frame rate affecting the fire rate of weapons and several weapons have had their baseline values changed. This update reduced the firing rate value of the Boltor from 11.7 to 8.8.

Originally the weapon shared the same icon and description as Braton, while the blueprint icon and in-game model shared that of Burston. As of a visual update on February 8, 2013, it now has a unique appearance and description.
